Corrections and clarifications + British Airways

An article on the current cabin crew dispute between British Airways and the Unite union's flight attendant branch Bassa, named Frank Burchill, a visiting professor at Strathclyde University, as the author of what we described as "a comprehensive guide to undermining Bassa's current leadership". That information was incorrect.

Professor Burchill was not commissioned to write, and did not produce or write this document. He had no involvement whatsoever in it. (BA told to hit union "where it hurts", 27 March, page 1).

We apologise to Professor Burchill for our error and for the distress or damage it has caused him.
